0003 If you have an in-vehicle device with the above configuration, for example, you can use it when you are away from your car for a long time. If the vehicle is damaged, the in-vehicle device itself may be removed and stored in a safe place. Therefore, damage caused by theft etc. can be prevented. However, it is necessary to remove and install such devices one by one. It is complicated, and transporting it is also a difficult task. Focusing on this point, A device in which only the operating section can be removed from the nose has been put into practical use. If you remove only the control part in this way, the device itself will be completely free without this control part. Even if the device itself is stolen, it cannot be used. I can't do it. This has the effect of preventing the device from being stolen. It's set.

[Problem that the idea aims to solve]

By the way, in the case where the operation section and the main body of the device are separate, it is necessary to remove the operation section. A spring member is interposed so that the operating section is separated from the nose when removed. child Although the spring member may be provided alone, it is necessary for the electrical connection between the operating section and the main body of the device. Many of them also have the function of a terminal member for connection. In this case, in order to make the spring member function as a contact point, its elastic force is Normally, the operating part and nose should be set to resist the elastic force of the spring member. It has a locking mechanism to keep it in place. Therefore, the operating section should be opened from the nose. When removed, the operating section will be biased by the elastic force of the spring member when the locked state is released. It had the disadvantage that it could easily fly out or fall. Therefore, this invention prevents the operation part from popping out or falling when it is removed. The objective is to provide in-vehicle equipment that is easy to install and remove.

[0005]

[Means to solve the problem]

The configuration of the present invention to achieve the above purpose is to The body and the operation section that provides operation information for the main body of the device are detachably separate bodies. For in-vehicle devices that are equipped with A biasing member, a locking portion that maintains the operating section attached to the device body side, and an operating section. is attached to the device, the operation section is magnetically attracted to the device. The device is characterized by comprising a magnetic adsorption portion for holding the device.

[0006]

[Effect]

The operation of the present invention with the above configuration is such that the operation unit is released from the attached state by the lock unit. When it is turned on, the operating section can be removed from the device body, such as the nose. in this case , a biasing force is applied to the operation unit by a biasing member to separate it from the main body of the device. At the same time, a magnetic attraction force is applied in the opposite direction by the magnetic attraction section. subordinate Therefore, the biasing force by the biasing member is canceled by the suction force by the suction part, and the biasing force by the biasing part is It will not jump out or fall due to the urging force of the material. In this way, the installation This makes it easy to remove.

【Example】

Hereinafter, the present invention will be explained with reference to the drawings. Figure 1 shows the equipment body and this node. Figure 2 is an exploded perspective view of the operating unit attached to the device; FIG. 2 is an enlarged cross-sectional view of the nose of The in-vehicle device 10 shown in FIG. disc player 11 and a separate unit that can be detachably attached to the nose 11a of this disc player 11. It is equipped with an operation section 12 configured as a. This nose 11a has an insertion hole 11b for the disk D on the upper side, and a hole 11b for inserting the disk D on the lower side as shown in the figure. Attachment part 13 of operation part 12 formed as a recess, left side of this attachment part 13 in the drawing In addition, a locking portion 15 etc. that maintains the attached state of the operating portion 12 attached to the mounting portion 13 is provided. It is provided. This mounting section 13 sends and receives operation signals to and from the operation section 12, which will be described in detail later. A pair of cylindrical columns that supply power to a part of the photoelectric conversion unit 13a and the operation unit 12 Terminal members 14a, 14a and a part of a magnetic attraction part, details of which will be described later, are provided. Ru.

[0008] A part of this magnetic attraction part includes a plate-shaped magnet 16, a U-shaped magnetic member 17 is arranged, and the magnet 16 is held between the legs of the magnetic member 17. It is installed. Among these, the open end of the magnetic member 17 is connected to the attachment part 13. The terminal members 14a, 14a are protruded from the nose surface, and the terminal members 14a, 14a are arranged on both sides of the nose surface. Ru. These terminal members 14a, 14a and a part of the photoelectric conversion section 13a are connected to the nose 1. It is attached to a common circuit board 18 disposed inside 1a. Among these, a part of the photoelectric conversion section 13a arranged on the device main body 11 side is a circuit board. The photoelectric conversion element designated by numeral 19 disposed on 18 corresponds to the operating section 12, which will be described later. A lens member 20 is arranged on the contact surface. In this embodiment, the operation section 12 and Operation information is transmitted and received with the device body using light, but known mechanical Contacts may also be used.

[0009] The lock portion 15 maintains the operating portion 12 attached to the mounting portion 13 in its attached state. A push button 15a that is slidably arranged in the direction of arrow A, and this push button 1 Due to the sliding of 5a, the locking portion is moved in the direction of arrow B and is further biased to the right in the figure. material 15b. The push button 15a is tilted at the contact portion with the locking member 15b. A protrusion 15aa with a slope is formed, and on the other hand, the protrusion 15aa and the The contacting locking member 15b is a claw portion 15c that locks a part of the left side surface of the operating section 12 in the drawing. and a claw portion 15d that comes into contact with the protruding portion 15aa. The illustrated operation unit 12 has a circuit board 24 arranged inside a case 27 made of synthetic resin. The switches 22, 36 and the display 21 are mounted on one side. and is arranged on the other side so as to be in contact with the terminal members 14a, 14a. to the terminal members 23, 23 and the photoelectric conversion element 19 disposed on the device main body 11 side. A light emitting section 25 that emits light is appropriately attached. Also, each of these configurations A corresponding notch is formed in the portion of the case 27 facing the component. further back On the surface of the case 27 facing the magnet auxiliary member 17, there is a A common plate-shaped fixing bracket 26 that comes into contact with the open end of the magnetic member 17 is removed. It is attached. In this embodiment, the fixing bracket 26, the magnet 16, The magnetic member 17 constitutes a magnetic attraction section 33 .

0010 The terminal members 23, 23 are in contact with the opposing terminal members 14a, 14a. It is a plate-shaped elastic member made of conductive spring metal that elastically deforms when In this example The terminal members 23, 23 also serve as a biasing member. Furthermore, this implementation In the example, we have shown a device that doubles as a biasing member and a terminal member, but each can be used as a separate body. may be configured. In this embodiment, the magnetic attraction force of the magnetic attraction part 33 is applied to a terminal member as a biasing member. The value is set to be slightly larger than the urging force of 23 and 23. Both of these Depending on the force relationship, the force required to remove the operating section 12 from the mounting section 13 can be arbitrarily set. It becomes possible to do so.

[0011] Assuming that the operation part of the in-vehicle equipment with the above configuration is to be attached and detached, This will be explained with reference to FIG. Figure 3 shows how the operating section is attached to the nose. 4 is a partially enlarged view of the portion indicated by the symbol C in FIG. 3. As shown in FIG. 3, when the operation section 12 is not attached to the mounting section 13, the operation The terminal members 23, 23 on the side of the portion 12 are in a state shown by the symbol (A) in FIG. In this state, no external force acts on the terminal members 23, 23, so the terminal members 23, 23 , 23 are in contact with the inner wall surface of the case 27. When attempting to attach this operating section 12 to the mounting section 13, the terminal members 14a, 1 4a comes into contact with the terminal members 23, 23. Due to this contact, the terminal members 23, 23 It is bent and deformed into the state shown by the symbol (b) in FIG. Due to this deformation, the operation section 1 A force is generated between the mounting portion 2 and the mounting portion 13 in the direction of separating the two. and, When the two are brought closer together, the open end of the magnetic member 17 touches the fixing bracket 26. comes into contact with. Due to this contact, the operating section 12 is magnetically attracted to the device main body 11. . At the same time, the lock part 15 (not shown in the figure) locks the operating part 12 and the main body of the device. 11 is in a locked state, and the operation part 12 and the device main body 11 are in the machine state. is maintained.

0012 When this operating section 12 is attached to the device main body 11, the terminal members 23, 23 The biasing force acts in the direction of separating the two, and on the other hand, the magnetic attraction of the magnetic attraction part 33 The attractive force acts to cancel the biasing force of the terminal members 23, 23. Next, when removing the operation section 12 from the mounting section 13, first lock the operation section 12 with the lock section 15. Release the locked state. In this state, the terminal members 23, 23 as biasing members are used. The urging force acts in the direction of separating the two, but the magnetic attraction force of the magnetic attraction part 33 As a result, the biasing force of the terminal members 23, 23 is deenergized, and as a result, a slight adsorption force is generated. I am using it. Therefore, the operating section 12 may jump out or fall from the mounting section 13. There's nothing wrong with that. In this state, when the operating section 12 is slightly separated from the mounting section 13, the magnetic member 1 The magnetic attraction force that acts between 7 and the fixing bracket 26 is proportional to the square of the distance. However, the biasing force due to the terminal members 23, 23 is reduced by this slight separation. The force of does not decrease. Therefore, in this embodiment, the operating section 12 is located slightly away from the mounting section 13. By separating them from each other, the operating section 12 can be removed extremely easily.

[0013] In the device of the embodiment described in detail above, the biasing member functions as a contact point. Therefore, even if it is necessary to set the elastic force to a certain degree, it is possible to dissipate that force. By applying the magnetic attraction force, the lock part 15 can be released as in the conventional case. When the operation unit 12 is pushed out or dropped due to the biasing force of the biasing member (terminal member). This prevents Therefore, if the biasing member and the terminal member are used together, However, the elastic force (biasing force) can be set arbitrarily. It should be noted that the present invention is not limited to the above embodiments, and may be modified within the scope of the gist. Various modifications are possible.

[0014] FIG. 5 is a sectional view showing another embodiment of the vehicle-mounted device. In addition, from the same figure onwards, the above-mentioned actual Items that are equivalent to those explained in the example will be given the same reference numerals and their explanation will be omitted. Omitted. The magnetic attraction part 30 shown in the figure is a support part formed protruding from the back surface of the nose 31. The support member 31a is rotatably supported around the open end of the support member 31a. A rotating member 32 and an open end of the rotating member 32 attached to the lower surface shown in the figure. A magnetic member 35 similar to that described above, and a magnet attached between the magnetic members 35. 34, a spring 37 that biases the rotating member 32 clockwise, and an operating portion 39 side. and a fixing bracket 26 provided at a position facing the magnetic member 35. We are prepared. Further, the open end of the magnetic member 35 of the nose 31 is exposed from the nose 31. It is designed to protrude from the surface.

[0015] The end surface 31b of the nose 31 that comes into contact with the operating section 39 at the right end in the figure is slightly protruded. A contact side surface 39 of the operating portion 39 is formed into a curved shape and comes into contact with the contact end surface 31b. a is formed in a corresponding concave shape. On the other hand, the end made of the above-mentioned elastic member The child members 23, 23 and the terminal members 14a, 14a are different from the above embodiments, and the child members 23, 23 and the terminal members 14a, 14a are It is provided offset to the end. In addition, the nose 3 on the left end side in the illustration of the operating section 12 1 is provided with a lock portion 38. The lock portion 38 includes a push button 38a that is slidably arranged in the direction of arrow A in the figure; The locking member 38 is pressed by the sliding of the push button 38a and slides in the direction of arrow B. b, and a spring 38c that constantly biases the locking member 38b in the right direction in the figure. It is something that has been learned.

[0016] The operation of the in-vehicle device having the above configuration will be explained with reference to FIG. 6. figure 6 is an explanatory diagram showing a state when the operating section is removed from the nose. When the operation part 39 and the nose 31 are in the attached state, the terminal members 23, 23 are attached. Against the force, the operating section 39 is mechanically maintained in the installed state by the locking section 38. Ru. When the locking state by the lock part 38 is released from this state, the operation part 39, due to the biasing force of the terminal members 23, 23, the uneven portion 31b at the right end in the figure, Rotate counterclockwise about 39a and remove. Along with this rotational displacement of the operating section 39, the rotational member 32 of the magnetic attraction section 30 also moves with the symbol ( It is rotationally displaced from the position shown in c) to the position shown in symbol (b). This is the operation section 39 The fixed bracket 26 and the magnetic member 35 are in contact with each other, and this suction This is because the force exerted by the spring 37 is set to be weaker than the force applied.

[0017] Then, after the lower end of the rotating member 32 in the drawing comes into contact with the inner wall surface of the nose 31, Furthermore, when the operation part 39 itself is moved by hand in the direction of removal, it rotates from the above-mentioned contact state. The member 32 is restricted from rotating, the magnetic member 35 and the fixing bracket 26 are separated, The magnetic adsorption force acting during this period rapidly decreases as described above. Then the rotating member 32 is retracted into the nose by the spring 37 as shown in FIG. 5, and the stopper 37 It stops when it hits a. In this way, the operating section 39 can be easily removed. Also , in this embodiment, the operating section 39 is separated from the nose 31 as shown in FIG. is held in an inclined state by the magnetic adsorption section 30, further improving its operability. can be raised. Even if in-vehicle equipment with such a configuration The same effect as in the example can be obtained.

[0018] FIG. 7 is a sectional view showing the configuration of a vehicle-mounted device as yet another embodiment. The difference between the in-vehicle device 40 shown in the figure and each of the embodiments described above is the configuration of the display. be. The display 41 shown in the figure has its light source 42 disposed inside the nose 43. , this light is guided by a lens 44. With this configuration, Even if there is, the same effect as in the above embodiment can be obtained. Furthermore, the example shown in the figure shows a case where the nose part and separate operating part are removable. However, the entire nose may be detachable from the main body of the device.
